Hypsipetes ganeesal, Jardine & Selby, 111. Orn. iii. pi. 148 (183- ?) . (Nee Sykes, P. Z. S. 1832, 



p. 86.) (Fig. et descr. orig.)

Diagn, — Superne olivaceo-bmnneus, inferne pallidior magisqne griseus ; vertice obscure nigricante ; 

 rectricibus simpliciter fuscis, latis. 



The diagnosis of Jardine and Selby contains several characters that are 

 not diagnostic, and therefore requires amendment. The very dull colour of 

 the head, the want of bands on the tail, and longer bill distinguish this 

 species readily from H. borhonicus ; but not less important is the breadth of 

 the rectrices, w^hich are nearly tw^ice as broad as in the kindred form. Its 

 size sufficiently points it out from H. madagascariensis. We must therefore 

 add : — 



Iridibus aurantiacis. Long, tota 10*5, alse 5, caudse 4*25, acrotarsi 1*4, dig. med. sine 

 ungue -85, ballucis sine ungue '51, maxillae a fronte '85, ejnsdem a rictu 1*06, mandibulse 

 ab articulo 1*65, rostri altitudo ad frontem '32 poll. Angl. 



A young bird of this species assuming the adult dress has still enough 

 of the nestling plumage left to allow of its description : the top of the head 

 and upper parts generally are of a dull hair-brown, tinged with fulvous 

 towards the rump ; the remiges and wing-coverts hght reddish-brown, 

 especially on the outer webs ; rectrices dull light reddish brown ; chin and 

 throat dusky white ; breast dull greyish brown ; belly lighter, becoming 

 dusky white about the vent. 



H, borhonicus and H. olivaceus resemble each other in having the inner 

 wing-coverts of a pale fawn-colour, and herein differ from H. madagascariensis 

 and from the remaining species.
